Does this work with the new firmware version 2.1.1_0159 exploit?

A new exploit for firmware version 2.1.1_0159 has been discovered here:
https://github.com/atc1441/ATC_MiThermometer

After flashing the 2.1.1_0159 exploit, can the normal OTA flashing procedure work to get this ZigBee firmware working?

Yes, it should work. After flashing to ATC firmware with that firmware you can convert it to zigbee according to the instructions

When trying to pair the device via bluetooth on Telink Flasher v6.2, I get the following errors:

And when trying to connect for a second time:

I used this web flasher tool successfully from the latest (as of 21/01/25) exploited firmware for 2.1.1_0159 https://pvvx.github.io/ATC_MiThermometer/TelinkOTA.html

Flashing the ATC_ota_40000.bin file took a long time (~300 seconds). I then removed the battery and re-inserted. I was then able to connect again and flash the z03mmc.bin file. The flash was a lot faster and rebooted into zigbee pairing mode. It was immediately available and connected to my Home Assistant server via ZHA.

The same method worked for me. Just finished!
